Intake structure of the hydraulic oil tank breather

摘要

(57) Abstract Objective As though it is the hydraulic system in the construction equipment at bulk,Furthermore in the hydraulic oil tank whose internal pressure change is considerable, especially negative numberInspiration the time of pressure quickly sucking/absorbing of the hydraulic pumpIt is and is packed and preventing the generation of the cavitation with the decrease of capacityThe breather cap which it tries to do is offered. Constitution In breather regardless of lift tonnage of air intake valveAs the air intake dedicated inflow path which makes the inflow of air intake possible the exhaust air valIt features that the air intake hole is provided in bu.
